[Interest] DBus on X11 using Qt5

[Ramakanthreddy Kesireddy]

Hi,

I would like to understand why the below code snippet doesnot works(Filesystem path doesnot returns any) in Ubuntu 12.04 minimal version where as  It works fine in Ubuntu 12.04 desktop version on target tegra3 device.


QDBusMessage Reply;
QDBusInterface* Connection= new
 QDBusInterface(DISK_SERV,HAL_MGR_PATH,DISK_SERV,QDBusConnection::systemBus(), this);

Reply = Connection->call("EnumerateDevices");

if( QDBusMessage::ReplyMessage == Reply.type())
{
QDBusArgument dbusarg = qvariant_cast<QDBusArgument>(Reply.arguments()[0]);
dbusarg.beginArray();

     while(!dbusarg.atEnd())
     {
       QVariant variant = dbusarg.asVariant();
       QDBusObjectPath dbusObjectPath = qvariant_cast<QDBusObjectPath>
            (variant);

       mFileSystemPaths.append(dbusObjectPath.path());
     }
     dbusarg.endArray();
    }

  delete Connection;

Please let me know if there are any dependencies on DBUS for the above code to work
On linux systems as this code retrieves the file system path like /dev/sda1 for example.

Thanks and Regards,
Ramakanth

Hi,

Please let me know how can we verify if DBus is working on X11(Ubuntu 12.04 Minimal)
or if there are any dependent packages to be installed for DBus.

Iam using Qt5.0.2 sdk.

Thanks and Regards,
Ramakanth
